average moult stage for 2cy October michahellis: Primary P10 is
fully grown and all the secondaries and rectrices are second generation
and complete. Hence, the complete moult has ended. After this complete
moult, a partial moult has included some of the tertials and wing-coverts.
In this individual, the fresh coverts and scapulars still show brown pattern, see e.g. the brown shaft streak and arrow-head pattern on the third inner greater covert. Brown patterns on grey based feathers can be found in the median coverts as well, and even the new scapulars are not completely plain grey. The old second generation central and outer greater coverts have relatively dense variegated pattern, colours reverse of the average michahellis: here the brown pattern dominates over the white spots.
